Is this image 'true color'?

Not sure....I think the true image was more Orange-Reddish, however Hubble has taken astounding images in true colours so I reckon it might be a real image as you'd see it in visible light

If it is the same image that was on the cover of Astronomy Magazine a few years ago, no. It is an NIR image taken by HST. There is a VL image I've seen. It does not show as much structural detail and there is very little color. Just white like a big thunder cloud here on Earth.

They show it as a visible wavelength image here (http://chandra.harvard.edu/photo/0099/). The image in the OP could be a composite NIR + visible.

Adding: But Im not saying russ is wrong.
